Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a conical two-lobed clamp for test bars. Background Technology

[0002] Currently, there are no products in China that can be described as "conical two-lobed clamps" in the technical field involved in this utility model. The closest implementation in related fields is a threaded and nut locking structure. However, this traditional locking structure has some shortcomings in practical applications, such as relatively cumbersome operation and slow clamping speed.

[0003] The "conical bipartite clamp" of this invention has significant functional and practical value. Its primary function is to enable rapid and convenient clamping of the specimen in a vertical position. This clamp utilizes the self-locking principle generated by the angle of the conical structure, locking the specimen in place with the weight of the specimen itself. Furthermore, the angle of the conical structure is less than or equal to the friction angle between the material of the conical structure and the material of the specimen, thus ensuring the reliability of the specimen clamping. The conical bipartite clamping blocks and the conical bore crossbeam are made of ceramic material, exhibiting good wear resistance and high-temperature resistance, which extends the service life of the clamp. The novel structure of this clamp provides new ideas and methods for the technological development of related fields.

[0004] Existing technical solutions suffer from cumbersome clamping operations and slow speed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a conical two-lobed clamp for test bars, which solves the technical problems of cumbersome clamping operations and slow speed in existing technical solutions.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a conical two-lobed clamp for a test bar, comprising a conical bore beam and a pair of conical two-lobed clamping blocks, wherein a conical hole is provided on the upper wall of the conical bore beam, and the pair of conical two-lobed clamping blocks are installed together in the conical hole; the conical hole on the conical bore beam is used to install the conical two-lobed clamping blocks to achieve the clamping function of the test bar.

[0007] Preferably, the pair of conical two-lobed clamping blocks are symmetrical in structure, the upper half of the pair of conical two-lobed clamping blocks after merging is a cylindrical structure, the lower half of the pair of conical two-lobed clamping blocks after merging is an inverted frustum structure, and a test hole is opened in the center of the pair of conical two-lobed clamping blocks after merging; these structural features help to better clamp the test rod.

[0008] Preferably, after the pair of conical two-lobed clamping blocks are combined, the conical structure's oblique angle forms a self-locking mechanism with the conical hole on the conical hole beam; this achieves the self-locking function and improves the stability of clamping.

[0009] Preferably, a test rod is provided in the test hole of the stack of the two conical clamping blocks, and the oblique angle of the conical structure formed by the combination of the two conical clamping blocks is less than or equal to the friction angle between the material of the conical structure and the material of the test rod; the relationship between the oblique angle of the conical structure and the friction angle of the material is emphasized to ensure the reliability of clamping.

[0010] Preferably, when installing the test bar, the test bar is placed in the conical two-lobed clamping block and then inserted into the conical hole of the conical bore beam.

[0011] Preferably, the material of the pair of conical bilobal clamping blocks and the conical hole crossbeam is ceramic material; it has certain wear resistance, high temperature resistance and other characteristics, which helps to improve the performance and service life of the clamp.

[0012] Beneficial effects

[0013] This invention provides a conical two-lobed clamp for test bars, which solves the problem of quick and convenient clamping of test bars in a vertical state, improving work efficiency. The conical structure utilizes its angled shape to create a self-locking mechanism, using the weight of the test bar itself to lock it in place, ensuring reliable clamping.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a conical two-lobed clamp for a test rod 5, comprising a conical bore beam 1 and a pair of conical two-lobed clamping blocks 2. The upper wall of the conical bore beam 1 is provided with a conical hole 3, and the pair of conical two-lobed clamping blocks 2 are installed together in the conical hole 3. The conical hole 3 on the conical bore beam 1 is used to install the conical two-lobed clamping blocks 2 to realize the clamping function of the test rod 5.

[0022] In this embodiment, the pair of conical two-lobed clamping blocks 2 are symmetrical in structure. After the pair of conical two-lobed clamping blocks 2 are combined, the upper half is a cylindrical structure, and the lower half is an inverted frustum structure. After the pair of conical two-lobed clamping blocks 2 are combined, a test hole 4 is opened in the center. These structural features help to better clamp the test rod 5.

[0023] In this embodiment, the pair of conical two-lobed clamping blocks 2 are combined and then self-locked by the oblique angle of the conical structure and the conical hole 3 on the conical hole beam 1; thus realizing the self-locking function and improving the stability of clamping.

[0024] This embodiment is further configured such that a test rod 5 is provided in the test hole 4 of the pair of conical bilobal clamping blocks 2, and the oblique angle of the conical structure formed by the combination of the pair of conical bilobal clamping blocks 2 is less than or equal to the friction angle between the material of the conical structure and the material of the test rod; the relationship between the oblique angle of the conical structure and the friction angle of the material is emphasized to ensure the reliability of clamping.

[0025] In this embodiment, the test rod 5 is further configured such that when installing the test rod 5, the test rod 5 is placed in the conical two-lobed clamping block 2, and then placed into the conical hole 3 of the conical hole beam 1.

[0026] In this embodiment, the materials of the pair of conical bilobal clamping blocks 2 and the conical hole beam 1 are ceramic materials, which have certain wear resistance, high temperature resistance and other characteristics, which help to improve the performance and service life of the clamp.

[0027] Its detailed connection methods are well-known technologies in this field; such as Figure 1-5 As shown, the test bar is placed between the two conical clamping blocks 2, and then the two conical clamping blocks 2 are inserted into the conical hole 3 of the conical beam 1. The angle of the two conical clamping blocks 2 matches the angle of the conical beam 1, utilizing the self-locking principle of the conical structure's angle to lock the test bar in place using its own weight. The angle of the conical structure is less than or equal to the friction angle between the material of the conical structure and the material of the test bar to ensure the reliability of the test bar clamping. The materials of the two conical clamping blocks 2 and the conical beam 1 are ceramic materials. This material selection has certain advantages, such as good wear resistance and high temperature resistance, which helps to improve the performance and service life of the clamp. Through this specific implementation method, this technical solution can achieve rapid and reliable clamping of the test bar 5, and has high practical value.
